PEI Polyetherimide TECAPEI Ensinger Plastics

Polyetherimide or PEI material is an amorphous thermoplastic with high mechanical strength and rigidity. PEI polymer is extruded by Ensinger in sheet and rod shapes using Sabic's Ultem® resin. Unfilled PEI thermoplastic is translucent and amber in color with exceptional mechanical, thermal and electrical properties. In filled grades, the addition of glass fiber reinforcement, coupled with Ensinger's proprietary extrusion techniques, provides users with a polyetherimide offering that has both greater tensile strength and rigidity, while also improving dimensional stability.PEI Ultem® plastic has similar characteristics to the polyarylsulphones, while simultaneously offering significant advantages. Polyetherimides has a remarkably high creep resistance over a wide temperature and a high permanent operating temperature. Furthermore, very good resistance to hydrolysis, along with dimensional stability rounds out the portfolio of polyetherimide properties.Pei Ultem Sheet Rod

TECAPEI™ GF30 Nat (Sabic Ultem®2300 Series)

PEI FILLED WITH 30% GLASS FIBER

This is a special 30% glass fiber reinforced PEI, manufactured by Ensinger under the tradename TECAPEI GF30 natural. In comparison to unfilled PEI (TECAPEI natural), PEI GF30 demonstrates high rigidity, very high mechanical strength, as well as extremely good dimensional stability, and good resistance to high energy radiation. These properties make PEI with 30% glass fibers suitable for use in parts that are exposed to high static loads over long periods in high temperature conditions.
